BUNDLING-PRESS.

Specification of Letters Patent.

Patented May 8, 1906.

Application filed April 29, 1905. Serial No. 258,034.

To all whom, t may concern,.-

Be it known that I, TALBOT C. DEXTER, a citizen of the United States, residing at Pearl River, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Bundling-Presses, of which the following is a specification.

My invention relates to bundling-presses, and is more especially concerned with a manually-operated bundling-press of novel construction for bundling signatures.

The object of my invention is to provide a manually-operated bundling-press which is simple in construction and eflicient in operation.

Various features of novelty will appear from the detailed description of my improved press with reference to the accompanying drawings, and these will be more especially set forth in the claims.

In said drawings, Figure 1 is a side elevation of a hand-operated bundlingpress embodying my invention. Fig. 2 is a front end elevation of the same. Fig. 3 is a plan view of the press as seen from above. Fig. 4 is a side elevation of the front head in detail. Fig. 5 is a rear elevation of the same. Fig. 6 is a front elevation of the rear head in detail, and Fig. 7 is a side elevation of the same. Fig. 8 is a detail view of one of the hand-levers and a detent operated by it.

Like reference-numerals are used to indicate the same parts in the various figures.

Referring now more specifically to said drandngs, 10 indicates the front frame, and 11 the rear frame, of my improved bundlingpress. A bar 12 is secured to the front and rear frames near the bottom, and at the top these frames have secured to them the trackbars 13 and 14. These track-bars 13 and 14 together support a hanger or bracket 15, which receives the forward ends of a number of bars or rods 16, forming the trough. The rear' ends of the trough-bars 16 are suitably secured in the rear frame 11. A bifurcated stay or brace 15 serves to brace the bracket 15.

Seated upon the trough-bars 16 are the front head 17 and the rear head 18, which are provided, respectively, with recesses 19 and 20, into which the trough-bars t. The front head 17 is provided with a pair of recessed earpieces 21 and -22, which iit over the track-bars 13 and 14 mentioned above, and the said track-bars 13 and 14, together with the trough-bars 16, thus form, as it were, tracks or ways upon which the front head 17 may slide.

In addition to the earpieces 21 and 22 the front head 17 is provided with a pair of lugs 23 and 24 on its rear surface, which have the perforations 25 and 26 for the purpose of attaching to them the press-operating mechanism, which will be described later. The front surface of the head 17 is provided with a plurality of transverse intersecting grooves 27, through which the operator may pass the cord in tying up the bundles of signatures after they have been pressed into compact form.

,The rear head 18 is adjustable and is provided with a pair of recessed earpieces 28 and 29, which fit over the track-bars 13 and 14 in a manner similar to the earpeces 21 and 22 of the front head 17. The earpieces 28 and 29, however, are provided with perforations 30 and 31, through which a shaft 32 passes. Secured to the ends of the shaft 32 are a pair of pawls 33 and 34, which are adapted to engage in racks 35 and 36 upon the rear portions of the tracl -bars 13 and 14 for the purpose of holding the rear head 18 in any position to which it may have been adjusted. A handle 37is secured to the central portion of the shaft 32 and may be operated to raise the pawls out of engagement with the racks 35 and 36. The rear head 18 is also provided with a number of transverse intersecting grooves 38 for allowing the operator to pass the cord around the bundles.

For the purpose of sliding the front head I pivot a pitman 39 to the perforated lugs 23 and 24, which is pivoted at its other end to a crank 40. The crank 40 is secured upon a shaft 41, which is ournaled in a pair of journal-studs 42 and 43 on the front frame 10. The shaft 41 may be oscillated by means of a segment-gear 44, which is fixed on said shaft and provided with gear-teeth 45. Mounted in suitable position upon the front frame 10 is a stud 46, which has secured t0 it a handL wheel 47 and also .carries a spur-gear 48, meshing with the segment-gear 44, and a ratchet-wheel 49. Fixed in the front frame 10 is a stud 50. The stud 50 has loosely mounted upon it a detent-pawl 51, engaging the ratchet-wheel 49, and this pawl has an upwardly-projecting lug which is engaged by a pin 52 of a hand-lever 53, loosely mounted upon the stud 50. This handlever operates by its pin 52 to raise the detent-paw1 51 IOO out of its engagement with the ratchet-wheel 49, thus freeing the pressing mechanism. For the purpose of preventing the hand-lever 58 from raising the detent by its own weight alone I attach one end of a spring 54 to the stud 50 by means of a screw or pin 55, the other end of said spring engaging the pin 52 in such a manner as to prevent the hand-lever 53 from being rocked by its mere weight.

In the operation of my improved bundlingpress the bundle of signatures is set upon the trough-bars between the two heads. The

position of the rear head is rst adjusted to suit the size of the particular bundle about to be pressed, and then the hand-wheel is turned until the front head has moved far enough to give the desired degree of compression to the bundle. The cord is then put around the. bundle, and after it has been tied the handlever is operated to raise the detent out of engagement with the ratchet-wheel and the pressure lowered, whereupon the bundle may be removed.

I do not wish to limit the scope of my invention to the exact details shown and described, as it is obvious that numerous modifications might be made for different purposes within the terms of my claims.

Having thus described my invention, the following is what T claim as new therein and desire to secure by Letters Patent:

l. In a bundling-press, the combination of a pair of end frames, a pair of track-bars supported in said end frames and having rackteeth formed on them for a part of their length, a pair of compression-heads mounted to slide on said track-bars, a pair of pawls mounted on one of said heads and engaging with the rack-teeth to hold said head in adjusted position, means for forcing the second head toward the first to compress the bundle between them, and suitable trough-bars for supporting the bundle to be compressed, substantially as described.

2. In a bundling-press the combination of a pair of end frames, a pair of track-bars rigidly mounted upon and connecting said end frames, a bracket depending from said trackbars near their front end, a bifurcated supporting-brace fixed at top to the bottom of the bracket and at bottom to the front end frame, a bundling-trough consisting of bars supported in front in the said bracket and at back in the rear end frame independently of the track-bars, a pair of compression-heads movably mounted on the track-bars and supported thereby independently of the trough-bars in position to operate in the trough, means for securing one of the heads upon the track-bars and means for moving the other head toward the secured head.

3. In a bundling-press, the combination of a suitable frame including a pair of trackbars, racks formed on a portion of said trackbars, a trough supported upon said frame parallel with the track-bars, a pair of compression-heads movably mounted upon the track-bars and supported thereby independently of the trough in position to operate in the trough, a pair of detents mounted upon one of said compression-heads in position to engage said racks, and operating means for moving the other head upon the track-bars.

4. ln a bundling-press, the combination of a suitable frame including-a pair of trackbars, racks formed on a portion of said trackbars, a bundling-trough supported upon said frame parallel with said track-bars, a pair of compression-heads movably mounted upon the track-bars and adapted to operate inthe trough, a shaft journaled upon one of the compression-heads, pawls or detents mounted upon said shaft in position to engage the racks of said track-bars, a controlling-handle secured to said shaft, and means acting upon the other compression-head to move it upon the track-bars.

5. In a bundling-press, the combination of a pair of end frames, a pair of track-bars mounted at their ends in said end frames, a bundling-trough consisting of bars supported at their front ends from the front end frame means of a suitable bracket and at their` by rear ends in the rear end frame independently of the track-bars, a pair of compression-heads supported on the track-bars independently of the bundling-trough and sliding within said trough, means for securing the rear head adjustably in position, and a hand-wheel, pinion, segment-rack, crank and pitman for forcing the front head toward the rear head to compress the bundle between them, substantially as described.
